Ammonia gas: to keep the air fresh, it is controlled below 20 ppm. Ventilation: 15 times/hour. Airflow: 20 cm/min. Cage utensil: the SPF corncob litter in the mouse cages (beijing aogaku synergetic feed limited) was exchanged once a week. Feed: the mice were fed with a maintenance feed (Jiangsu province cooperative medical bioengineering Co., ltd.) for the nitrogen-packed C060 irradiation laboratory mice. The mice were free to ingest and drink water. The mice take food mainly at night, are filled with feed and drinking water at 15 pm every day, and check at 8 am every day to supplement feed for the feed deficiency cage. And (3) drinking water: the drinking bottle is washed every 3 days, and the fresh and clean drinking water is added in time.
3.3 grouping of mice and behavioural detection
13 APP/PS1 negative male mice served as a blank control group (Blank control group, CON), and 64 APP/PS1 male experimental mice were divided into 4 groups according to the random block method: model group (MOD), compound low dose group (Low dose group powder, LDG), compound high dose group (High dose group of powder, HDG), donepezil group (DON) hydrochloride, 16 each. The spontaneous alternation of Y maze experiment and new object identification experiment after 7 days of adaptive feeding evaluate the memory and exploratory ability of each group of mice before drug intervention.
(1) Y maze spontaneous alternation experiment (Y-maze Spontaneous Alternation Test, YSA)
The mice in each group were tested by Y maze test before and after the administration. The Y labyrinth device consists of three black opaque support arms which are 35cm long, 5cm wide and 15cm high and have an included angle of 120 degrees between the arms, and the tail ends of the three arms are stuck with different pattern marks. And a layer of padding is thinly paved at the bottom of the Y maze, and the padding is uniformly stirred and mixed before each mouse experiment so as to eliminate the interference of the walking route and smell of the previous mouse. The three arms are in turn labeled A, B, C, and the mice alternately explore three different arms (e.g., ABC, ACB, BAC, BCA, CAB, CBA) as the actual number of transitions (alternations). Non-alternating exploration of three different arms (e.g., BCB, ACA, BAB, etc.) does not account for the number of transitions. The total number of arm entries is explored minus two times as the maximum number of transitions.
The room was kept quiet during the experiment, and each mouse was placed in the Y maze for 5min before the formal experiment. After 1h interval, the formal experiment is started, mice are put into the Y maze A arm, and the head direction of each mouse is ensured to be consistent. The software monitors and records the total number of times (N) the mice entered the three arms over 5 minutes and the order of entering the arms. The mice were serially entered into 3 different arms for 1 correct alternating reaction, while the number of correct alternating reactions was recorded. Spontaneous alternation accuracy (%) =correct alternation reaction number/(total number of entries into three arms-2) ×100%. The free alternation response rate is an index for evaluating the short-term memory ability (working memory), discrimination ability of spatial position sense and orientation sense, and segment memory of the mice.

5.1 behavioral baseline data analysis of groups of mice prior to drug intervention
The study tested and quantified the degree of cognitive deficit in APP/PS1 mice by Y maze spontaneous alternation experiments and new object recognition experiments. The spontaneous alternation experiment of the Y maze is a behavioral test for detecting the willingness of rodents to explore new environments, the action ability and the short-time working memory ability. Rodents generally prefer to explore new areas rather than familiar areas, which are related to brain area functions such as the hippocampus, prefrontal cortex, basal forebrain, and diaphragm. The new object recognition experiment is a behavioral test for detecting the recognition memory capacity of rodents (such as mice) based on the principle that the rodents like exploring new things and generating trend behaviors, and the experiment process does not cause strong boring factors (such as water intolerance, electric shock and the like) of the mice, does not generate bad stimulus to the mice, and is more objective. New object recognition experiments can study the exploratory capacity and short-term non-spatial near memory capacity of mice, and evaluate the integrity and attention of visual object recognition memory of animals. Y maze spontaneous alternation accuracy (z= -3.267, p=0.001 < 0.05) and new object cognition index (t=3.65, p=0.00 < 0.05) were lower for APP/PS1 group mice than for CON group (fig. 1A, 1B) (×p < 0.01, ×p < 0.001, compared to CON group). APP/PS1 mice were divided into MOD group, LDG group, HDG group, DON group according to the random block method, the Y maze spontaneous alternation accuracy of 4 APP/PS1 mice was not statistically significant to the difference of the new object cognitive index total score value (f=0.040, p=0.989 > 0.05), and the Y maze spontaneous alternation accuracy of 4 APP/PS1 mice was lower than that of CON group (P < 0.05) with the new object cognitive index total score value (fig. 1C).
